PUMP.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed March 13, 1915. Serial No. 14,053.

citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

invention relates to improvements in pumps and is particularly directedto an improvement in the driving mechanism and manner of arranging the same.

The principal object is the provision of driving gearing for a pump, the gear parts being mounted in a housing or casing in which a suitable quantity of oil is placed and arranged so as to transform a rotary motion into a reciprocating motion, the gearing itself being covered and protected from damage, but the connections with the pump proper being easy of access for installation and repairs.

Another object is the provision of an air compressor operated coincidently with the pump. 7 i

A further object is the provision of an antifreezing set-length whereby the air compresser head, etc.,may be-disposed below the frost line.

A further object is the improvement in details of construction and arrangement, whereby a simple and efiiciently operated driving mechanism for pumps is provided.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consists in the construction, combination and arrangement of parts hereinafter described and then sought to be defined in the appended claims, reference being made to the accompanying drawings, forming a part hereof, and which show merely for the purpose of illustrative disclosure a preferred embodiment of my invention, it being understood, however, that, in practice, various changes may be made within the scope of the claims, without digressing from my inventive idea.

Referring now to the drawings,

Figure l is a perspective view of my invention applied to a pump, parts being broken away to facilitate disclosure.

Fig. 2 is a perspective view, parts being shown in section of the discharge or stufiing box head and air compressor.

Fig. 3 is an elevation showing an antifreezing set length in position.

Referring now to the drawings, the numeral 1 designates the basemembers, which are shown in the form of a pair of spaced channel beams of suitable size and length. 2 designates the power unit shown in the form of an electric motor, suitably secured pinion or gear 7, which meshes with the larger gear or pinion 8 rotatable on stud shaft 9, which is securely fastened in the side of the casing. This larger gear wheel 8 has the pin 10 secured thereto, having the roller 11 rotatably mounted thereon, this roller being movable in the elongated slot .12 of the long arm 13 of the bell crank lever 14 which is journaled on short shaft 15, and has its shorter arm 16 projecting outward beyond the end of the casing as shown in Fig. 1. It is seen therefore, that by the rotation of the gear 8, the shorter arm of the bell crank lever will be given a reciprocat-' ing motion up and down. A suitable quantity of oil is adapted to be placed in the casing or housing 3, so that the parts will always be thoroughly lubricated, the gear wheel and bell crank lever raising the oil during their various movements in the casing or housing.

To the shorter arm of the bell crank lever, is connected the casting 17 which is in the form of an elongated arm having a socket member 18 provided thereon, this casting being secured to the shorter arm of the bell crank lever by means of bolt 19 and pin 19'. At the outer end of this casting 17 is pivotally connected a link 20 for operating the pump rod 21, which reciprocates in a suitable stuffing box head 22, which latter is detachably connected to the base members 1 as shown. A suitable connection 23 is also provided, whereby the air compressor may be operated. o

It is to be noted that the parts are arrangedso that the speed of the pump rod on the down stroke is greater than its speed on the up stroke, so that when doing the most work, that is on its upward stroke, the

plunger moves slower, but the average speed in revolutions per minute, is kept comparatively constant.

As shown in the drawings, the crank pin 10 moves through an angle of approximately 146 on the down stroke and an angle of 214 on the up stroke, or in other words, about 50% more time is required for the up stroke of the pump than for the down stroke.

noise and wear, than if the points were not run in oil.

A suitable belt tightening device may be used in connection with the belt between the power unit and the pulley 6, so that the operation maybe controlled, as desired.

The socket member 18 on casing 17, is for the purpose of receiving a handle 25 as shown in dotted lines so that the pump may be operated by hand should it be necessary or desirable.

The arrangement of the parts, including the power unit or the base members 1 provides a simple and strong construction. Its

mounting in position for work is a simple matter, as is its connection to the parts to be operated.

Another feature of my invention resides in the discharge or stufling box head including an air compressor and previously designated' 22. This is shown in detail in Fig. 2, the parts bein adapted to be positioned between the mem' ers 1, as shown in Fig. 1 of the drawings. 26 designates the head having an opening for the well connection and the discharge connection 27 to the system and the air receiver 28. This head 26 has the flange 29 whereby it is secured to the base members 1. Mounted in the enlarged aperture 30 in the upper side of this head is the stuffing box including the cylindrical member 31 having the tapered annular flange 32 fitting the tapered walls of aperture 30 and having the guiding sleeve or portion 33 within which the pump rod 21 operates. The base in this stufiing box is en- "larged to receive packing gland 34 and the packing between the gland and the guiding sleeve 33, thegland being held in place by the'adjustable connection 35 and the cylindrical member 31 being held in position by clamping members 36 and the adjustable connection 37 shown as a nut.

The air compressor is mounted on one side of the head includes the cylinder 38, piston 39, operated by connection 23 previously referred to, compression and inlet compartment 40, having inlet nozzle 41 controlled by check valve 42 and pet cock 43; the compressor also includes the discharge compartpossible efiiciency by eliminating all clearance loss, as the water fills the space in the compartment 40 and cylinder when the piston or plunger completes its discharge stroke, thereby forcing a maximum quantity of air into the system. It is to be noted that the air inlet is located just below valve 46-so that the air is drawn in adjacent the valve and on top of the body of Water in compartment 40 and that the quantity of air admitted may be controlled by the pet cock. The provision of this construction of stuffing box facilitates and simplifies the mount- 1 ing of the pump in position for well work and permits the ready detachment of the connections for examination or repair. It is also readily adaptable. for service below the frost line, this arrangement being shown in Fig. 3 of the drawing.

For this purpose, I provide the plate or disk 47 adapted to be secured to the beams or base members 1 and having the spacing sleeve or pipe 48 screwed thereinto. This spacing sleeve or pipe has the yoke member 49 secured to its "lower end and to which the head 29 is adapted to be connected. Of course the necessary extensions are provided for the pump rods.

This arrangement ermits the installation of the head in an out uilding where no heat is available, as the parts of the system and pump containing water may be located 'in a pit or other frost proof inclosure at a su cient depth to prevent freezing. I call this construction an I anti-freezing setlength.

What I claim is,-

1. A mechanism of the character described including in'combination a base or support, a driving means mounted thereon for operating a pump, a pump rod connected to said driving means, a head secured to said base or support, said head having a stuifing box for said pump rod provided by a cylindrical member having a tapered edge to fit a corresponding aperture in said head, a packin gland within said cylindrical mem ber an means for holding said cylindrical member and said gland in position. v
